The primary covariate, CSA, is derived from a question in the conduct disorder section of the interview (not administered to parents, for whom data were thus not included in the current analyses): “Before age 18, were you ever forced into sexual intercourse or any other form of sexual activity?” A follow-up question determined the age at which forced sexual activity first occurred. Two respondents (N=2) who endorsed the forced sex question, but reported its first occurrence at an age ≥18, were excluded from analyses (Nelson et al. 2002; Nelson et al. 2006). Seven individuals whose responses to this item at subsequent assessment were inconsistent (3 endorsed and then denied; 4 denied and then endorsed) were also excluded from further analyses. As we have done previously (Nelson et al. 2002; Nelson et al. 2006), those reporting forced sexual activity with first occurrence before age 18 (N=151) or who did not report (N=5) age of first occurrence were coded as having a history of CSA.
